ruby - Ruby 库来阅读 Apple Numbers 文档？

Question

有几个 Ruby 开源库可用于读取 Microsoft Excel 文件，例如roo或 电子表格。Apple Numbers 文档呢？有什么可用的吗？

这样的图书馆显然不存在（还没有？）。目前一个好的解决方法是通过 applescript 自动转换为 CSV，然后读取此结果，而不是尝试直接读取 Numbers 文件。不过，这可能不适合每个人的需求，但对我来说非常有效。

这是小程序：

# -------------------------------------------------------------------------------
# Command-line tool to convert an iWork '09 Numbers
# document to CSV.
#
# Parameters:
# - input: Numbers input file
# - output: CSV output file

on run argv
    # We retreive the path of the script
    set myPath to (path to me)
    tell application "Finder" to set myFolder to folder of myPath

    # We get the command line parameters
    set input_file to item 1 of argv
    set output_file to item 2 of argv

    # We retreive the extension of the file
    set theInfo to (info for (input_file))
    set extname to name extension of (theInfo)

    # Paths
    set input_file_path to (myFolder as text) & input_file
    set output_file_path to (myFolder as text) & output_file

    if extname is equal to "numbers" then
        tell application "Numbers"
            open input_file_path
            save document 1 as "LSDocumentTypeCSV" in output_file_path
            close every window saving no
        end tell
    end if
end run

像这样使用它：

osascript convert_to_csv.scpt input_file.numbers output_file.csv
